A worker in the high-tech greenhouses of H2orto Ostellato, Italy. With a size of 31 hectares, this is the largest hydroponic greenhouse in southern Europe. 220km of low power LED lights allow for winter production, ensuring all-year-round harvesting. The greenhouse operations are based on the principles of circular economy. At the end of the life cycle, plants become the fuel for the biogas plant that powers the greenhouse. Tomatoes are grown in a controlled environment, safeguarded from external pollutants, therefore there is no need for herbicides and glyphosates. Thanks to hydroponic growing, land usage is reduced to only one-tenth of traditional farming and water usage is reduced by 70%.
